From Michigan, USA:
Does one unit of the new Humalog "cover" the same amount of carbohydrates as one unit of Regular?
Theoretically one unit of lispro insulin (Humalog®) should "cover" the same amount of carbohydrate as 1 unit of Regular insulin, only faster. If however, you are a person in whom Regular lasts 10-16 hours, and Humalog lasts only 3-5 hours, you may need less Humalog to "cover" the same amount of carbohydrate and more "basal" insulin to cover basal insulin requirements as the Regular may have been both providing "coverage" for carbohydrate and basal insulin needs. If you are a person in whom Regular lasts 4-6 hours, than you are more likely to find that 1 unit of Humalog will "cover" the same amount of carbohydrate as 1 unit of Regular, only faster.
When switching to Humalog, you should work closely with your own physician to determine whether or not you can just substitute 1 unit of Humalog for 1 unit of Regular, or whether other adjustments need to be made.
